Anyone have experience with Respiratory Infections in cats and Clavamox?

Baci (4 year old neutered sphynx cat) is on Clavamox now (for a respiratory infection that we can easily hear when he gets excited but that the vet could not hear when he was paralyzed with fear in front of her).

He gets 2 pills each day of 62.5mg Clavamox....but the gunk inside his lungs (we think) seems to be taking a long time to clear. He's been on it for a full week and you can hear (sounds a bit phlegmy) that he's still having occasional trouble with easy breathing when he gets excited. When He's settled he's fine. Although less often now, he will still sneeze 15-25 times in a row at least once a day. Carmy loves the mucous and other beautiful substances that are now landing everywhere- -lemme tell ya. He's supposed to be on the meds for 3 weeks.

We will likely call the vet in the next day or so but was wondering if members had any advice on this. Thx!

This we site said URI is airborne and other health cats can get it. I was wondering could your record your cat breathing so the vet could hear that way? I took my last dog to the vet because he has not eaten for two days and he ate for the vet . My vet told he see pets do this all the time , as soon as the pet get to the vet they say "look I am fine I am eating , now can I go home?"

He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
